The whole is greater than the sum of its parts. Or is it? Gestalt psychology suggests that in a split second our brain amalgamates the parts of an object or form, and sees a whole. In other words, it turns perception into knowledge. But what happens when the artist disrupts that split second and the transition from perceiving to knowing is stalled? The artists presented have all used the liminal state of perception as a means of questioning what is in fact, known. Each work selected possesses a form of dissonance between the expected and the real, enabling a dialogue between artwork and viewer born out of confusion and failure to see a whole at once.
